ZETH

ZETH is a level editor for Doom engine games, aimed specifically at ZDoom source port. It is based on DETH and was created by Marisa Heit (Randi). ZETH is compatible with Doom, Doom II, Heretic, and Hexen.

Because ZETH 4.17 was published at a time when ZDoom was at version 1.23 beta 33, it is a bit quirky in that when a ZDoom-specific level is saved, any lump types introduced since then (e.g. DECORATE, KEYCONF, DEHACKED, or TERRAIN), if present, will be unceremoniously deleted. However, it will leave the five original Hexen lumps (MAPINFO, ANIMDEFS, SNDINFO, SNDSEQ, and BEHAVIOR) intact. This can be worked around by finishing the rest of the map first, testing and polishing the layout and play balance, and finally adding the newer lumps with a utility such as SLADE 3.

Its latest version features support for Linux and Windows (apart from DOS) and is sometimes referred to as WinZETH.
